摘要

Disclosed are a method and an apparatus for multiplexing/demultiplexing video data. According to the present invention, the method for multiplexing the video data comprises the step of adding a reproducing state of a CRA picture, that is, a predetermined syntax for indicating whether or not there is general reproduction and reproduction using a random access, to a header of a transmission unit data which multiplexes the CPA picture used for the random access.
